Mercury's surface in "enhanced color," a color scheme created to emphasize color differences. This is not what Mercury would look like to the human eye, but by applying mathematical analysis to images, color differences can be accentuated beyond those visible to a person.
Mount Rushmore National Memorial under construction.
The workers had to endure conditions that varied from blazing hot to bitterly cold and windy. Each day they climbed 700 stairs to the top of the mountain to punch-in on the time clock. Then 3/8 inch thick steel cables lowered them over the front of the 500-foot face of the mountain in a "bosun chair." Despite the dangers, no one was killed during the project.
Otters in Glacier Bay National Park and Preserve, Alaska.
The sea otter population of Glacier Bay has increased dramatically in the past 20 years. Ecologists consider sea otters a keystone species here. Otters consume vast quantities of clams, urchins, crabs, and other invertebrates and their presence creates ripples through the ecosystem. NPS photo.
Every day someone like you becomes a wildland wildfire fighter, a teacher, a trail-builder, a museum curator, or a park ranger. Discover your opportunities in national parks. Come to play. Come to learn. Come to serve. Develop your environmental leadership skills. Find a job. Be the next generation to preserve and protect these great places.
With more than 80% of Americans living in urban areas, urban parks are more important than ever. The father of American landscape architecture, Frederick Law Olmsted, said of urban parks:
It is one great purpose of the Park to supply to the hundreds of thousands of tired workers, who have no opportunity to spend their summers in the country, a specimen of God's handiwork that shall be to them, inexpensively, what a month or two in the White Mountains or the Adirondacks is, at great cost, to those in easier circumstances.
Interior Department Selects New Members for BOEM Scientific Committee
WASHINGTON — Secretary of the Interior Ken Salazar and Bureau of Ocean Energy Management (BOEM) Director Tommy P. Beaudreau today announced the appointment of 15 experts representing diverse scientific fields as members of the Outer Continental Shelf (OCS) Scientific Committee – a group that advises BOEM on the agency's offshore environmental studies, which inform policy decisions regarding development of Outer Continental Shelf energy and mineral resources.
“The membership of this important committee is made up of distinguished scientists representing several disciplines to advise the Department on the scientific integrity of BOEM's research,” said Secretary Salazar. “This is another important step as we continue to move forward with offshore energy development in a responsible manner guided by the best science, and I appreciate the members' willingness to contribute their time and their expertise to this important effort.”
“It is critical that we have robust, reliable and forward-looking information as we make decisions regarding future energy development,” said Director Beaudreau. “This committee supplies critical input on our research priorities and provides an external peer review to ensure our science remains world-class and that we are appropriately addressing the information needs of the bureau and the department.”
OCS Scientific Committee members are selected based on their expertise and reputation in the scientific community and ability to represent important elements of BOEM's research and science information needs. Members serve a three-year term and may not serve more than two consecutive terms. After a two-year break in service, a member is again eligible for appointment.
The committee's next meeting is expected in spring 2012, at which time they will select the chair. The committee meets at least annually, and meetings are open to the public.
